Samarasinghe, Kasun and Voigt, Thiemo and Mottola, Luca and Roedig, Utz (2011) Network Coding with Limited Overhearing. In: 8th European Conference on Wireless Sensor Networks (EWSN2011), 2011-02-23 - 2011-02-25.
The two key benefits of network coding are increased reliability and throughput. Most network coding approaches for wireless networks rely on overhearing neighboring transmissions. Overhearing in sensor networks, however, is not energy-efficient. In this paper, we extend GinMAC, a state-of-the-art MAC protocol, applying network coding with limited overhearing. Our approach reduces the delay allocating less retransmission slots. Our results show that network coding with limited overhearing reduces the power consumption of GinMAC while maintaining the desired level of reliability.
